Nice picture, but the highlights on the model's face are a little too strong for my taste.
Also I would personaly like to see her looking a little more towards camera, or maybe alter the position of her right arm slightly. Something about the shape of that arm does not look comfortable.
I like the textured effect on the background.

The picture is slightly too large for me to see it all on my monitor, making it difficult to judge the overall effect. The crop I see on my screen extends from just above her head to just below her left hand, and this makes a nice shape, so I am guessing that the overall effect of the image is also good.
